Service





1. Remove the intake manifold covers (Figure 1, Point 4) and the intake air distribution housing (Figure 1, Point 3) from the engine in order to access the vacuum T-piece. See ElsaWeb for repair procedure.











2. Replace the T-piece (Figures 2 & 3, Point 1), including the vacuum hose (Figures 2 & 3, Point 2). Use vacuum hose 06A 145 718 H (Figures 2 & 3, Point 2) as a replacement without hose clamps (Figure 4).

Note:
The vacuum hose 06A 145 718 H is 170 mm long and needs to be cut into 5 pieces of 30 mm in length. Use only one 30 mm piece per vehicle. Assemble this vacuum hose (Figures 2 & 3, Point 2) with the T-piece prior to installation.

3. Use hose clamp N 024 528 1 (2x) to secure both silicone hoses on the T-piece (Figure 4). Always use new hose clamps.

4. Reinstall the intake air distribution housing. Use 2 new hose clamps (N 024 505 4) for the two front connections (Figure 1, Arrows).
